Special-interest groups are organizations that focus on a particular issue or cause. PACs (Political Action Committees) and ORGS (Organizations) are two types of special-interest groups. PACs are typically funded by individuals, corporations, or unions and are used to influence the outcome of elections. ORGS are usually non-profit organizations that advocate for a specific cause or issue. Both PACs and ORGS are important in influencing public policy and shaping public opinion.
